I get it, and it's a good one..
But really, if you are at all worried about losing all your money in crypto, then you should only invest a little, and..
sell 50% once you 2x..
or sell 20% once you 5x...
depending on how worried/patient you are.
or any combination you're comfortable with so that losing "1x" will not put you worse than you started.
Can't afford a whole bitcoin? Buy a half, or a quarter, or an eigth and apply the same strategy..
Yeah, of course it could go to zero before you gain, but really, it's not looking like it. There has not been a better investment opportunity in our lifetime as what we're seeing now.
I think it's crazy that so many people who know about it are still hesitant to put even a modest amount in for fun.
